    Default What to do to a 308 that been sitting for at least 5 years?

    As the title suggests I have a 308 that's been sitting in the HJ ute for at least 5 years in a paddock, it's been stored without the carburetor on it so not sure what I should do with that, I figure a complete oil change, new fuel, new battery, new filters and such, what else would you suggest? What oils should I use Penrite for what? should I use a lead additive or will it be fine? Sould I also change the oil in the trans? anything else? Sorry for all the probably silly questions but this is my first project and I'm starting from scratch.

    First off you have to determine if anything has gone down the intake, if ok pull the oil pump off and coat the gears with a good coating of white petroleum grease[ Vaseline] prime the oil system with a good zinc based oil but I would use a good break in oil like Lucas break in 30w. you should be golden. But use common sense with everything and no short cuts.

    Check that it turns over by hand first... it may have seized.

    Due to additives in ALL oils ,oils break down ie they don`t lubricate well that's why u have a time limit between oil changes .
    Include diff /trans oil +coolant and brake fluid flush and bleed

    Pull plugs 1 or 2 squirts of oil in each cylinder and wind engine over .
    change plugs
    check plug lead resistance 5000-8000 ohms per foot
    inspect dizzy cap and rotor
    place 2-4 drops oil down centre shaft of dizzy [to lube advance weights mech]
    [ Optional but strip and relube dizzy shaft and weights would be best ]
    new point and condenser

    new fuel in tank with fuel treatment
    all new filters

    Take starter and altenator to a good sparky have new brushes bearings and lube and then bench tested

    Inspect all suspension rubbers as deterioration occurs regardless if u use vehicle or not

    Storing on concrete floor compared to grass can give 2 different outcomes . The moisture in the grass can cause A LARGE amount of corrosion internally/externally.

    As u are aware storing on grass is not the best .
